DS26LV32AT
3V Enhanced CMOS Quad Differential Line Receiver
General Description
The DS26LV32A is a high speed quad differential CMOS re-
ceiver that meets the requirements of both TIA/EIA-422-B
and ITU-T V.11. The CMOS DS26LV32AT features typical
low static I
CC
of 9 mA which makes it ideal for battery pow-
ered and power conscious applications. The TRI-STATE
®
enables, EN and EN*, allow the device to be active High or
active Low. The enables are common to all four receivers.
The receiver output (RO) is guaranteed to be High when the
inputs are left open. The receiver can detect signals as low
as
±
200 mV over the common mode range of
±
10V. The re-
ceiver outputs (RO) are compatible with TTL and LVCMOS
levels.
